(Chloromethyl)pentacarbonylmanganese(I): A crystal structure with a non-crystallographic centre of symmetry

摘要

There are two molecules in the asymmetric unit of the P21/c unit cell of ClCH2Mn(CO)5, the first halomethyl complex of manganese to be structurally determined. The molecules are crystallographically independent, despite an apparent local centre of symmetry. The average bond parameters include Mn-Calkyl 2.128(8) ?, C-Cl 1.811(8) ? and Mn-C-Cl 116.4(4)°.
